Common Preacher Curl mistakes
Hyperextending elbows at bottom - risks injury.
Letting your elbows drift wide during the Preacher Curl shifts load onto your shoulder joint instead of your Biceps brachii (especially long head). Keep them tucked at about 45 degrees to protect your rotator cuff and keep tension where it belongs.
Lifting butt off seat - reduces isolation.
Losing hip position during the Preacher Curl shifts the loading pattern away from your Biceps brachii (especially long head) and can compress your lower back. Stay planted and let your Biceps brachii (especially long head) do the work.
Using too much weight causing swing - defeats purpose of exercise.
Bouncing or using momentum during the Preacher Curl takes work away from your Biceps brachii (especially long head) and puts your connective tissue at risk. Control the weight through the full range — if you can't, lower the load.

How to Program the Preacher Curl
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 reps. Rest 60 seconds.
